Offaly A total of four proposed Natural Heritage Areas (pNHAs), three designated NHAs and two Special Areas of Conservation (SACs) occur within 10 km of the site. The pNHAs are as follows: • Lough Ennell • Raheenmore Bog • Grand Canal • Rahugh Ridge (Kiltober Esker) The NHAs are: • Black Castle Bog • Cloncrow Bog • Milltownpass Bog The SACs are: • Lough Ennell • Raheenmore Bog Some sites have more than one designation. So, for example, Lough Ennell has been designated as a pNHA under the Irish Wildlife Acts and as an SAC under the E.U. Habitats Directive. The proposed development site does not lie within or adjacent to any site that has been designated for nature conservation. There are no designated sites within 5 km of the development site, with the nearest designated site being Milltownpass Bog NHA, some 5.51 km to the north. The Grand Canal NHA and Raheenmore Bog SAC/pNHA both lie to the south of the development and are 7.09 and 7.12 km from the site respectively. Cloncrow Bog (New Forest) NHA lies directly to the west, beyond Tyrrellspass, 7.79 km from the site. Black Castle Bog NHA is some 8.43 km to the southeast of the site with Lough Ennell SAC/pNHA 9.56 km to the northwest. At 9.75 km, Rahugh Ridge (Kiltober Esker) pNHA is the furthest designated site that lies with 10 km of the proposed development. 6.3.2 Habitats, Botanical Species & Water Quality in the Existing Environment For inspection purposes only. Consent of copyright owner required for any other use. Habitats The wider Drumman site is a relatively uniform site, being an area of bog that has been cutover in the recent past. There are areas of bare peat, patches of Birch woodland and small areas of standing water. The development site boundary is confined to an area dominated by Birch in the western portion of the wider Drumman site. The surrounding landscape is largely cutover bog with the Mongagh river lying just north of the site. The R400 road lies to the southwest of the site and is bordered by a high treeline that comprises of mostly Monterey Pines (Pinus radiata) with some Poplars (Populus sp). A total of three habitat types were identified within the Drumman site boundary. The habitat types and their habitat codes (after Fossitt, 2000) are given below. The extent of the habitats is shown in Figure 6.2 and described further below. The habitats recorded are: • Cutover Bog (PB4) • Bog Woodland (WN7) • Recolonising Bare Ground (ED3) Cutover Bog (PB4) The Drumman site is situated within a cutaway bog area that has been commercially harvested for its peat resource in the recent past and this habitat type is the dominant one present on the site. Much of the area consists of bare peat that has a uniform surface consistent with mechanical harvesting of the peat. Other sections are being re-colonised by vegetation and even some scrub development.

Offaly Table 6-1 Summary of Designated Sites within 10 km of the proposed development Distance from Designated Site Site Code Reason for designation site (km) Milltownpass Bog NHA 002323 Milltownpass Bog NHA is a site of considerable conservation significance comprising as it does a raised bog, a rare habitat in the E.U. and one that is becoming increasingly scarce and under threat in Ireland. This site supports a 5.51 good diversity of raised bog microhabitats, including hummocks and pools and due to its easterly location, is of biogeographical importance. Grand Canal pNHA 002104 The Grand Canal is a man-made waterway linking the River Liffey at Dublin with the Shannon at Shannon Harbour and the Barrow at Athy Otter spraints are found along the towpath, particularly where the canal passes over a river or stream. The Common Newt breeds in the ponds on the bank at Gollierstown in Co. Dublin. The 7.09 Rare and legally protected Opposite-leaved Pondweed (Groenlandia densa) (Flora Protection Order 1987) is present at a number of sites in the eastern section of the Main Line. The ecological value of the canal lies more in the diversity of species it supports along its linear habitats than in the presence of rare species Raheenmore Bog SAC & pNHA 000582 This raised bog developed in a small basin in the catchment of two major river systems i.e. the Brosna and the Boyne. The bog has a well-developed hummock and hollow system. Raheenmore Bog is within the breeding territory of a pair of Merlin, a scarce species in Ireland and one that is listed on Annex I of the EU Birds Directive. Other typical bogland birds which breed include Red Grouse and Snipe. 7.12 Raheenmore Bog is a classical example of a Midland Raised Bog and the deepest remaining in Ireland. The site is remarkably intact and is one of the few raised For inspection purposes only. bogs where Consentrestoration of copyright of owner the requiredlagg zonefor any otheris feasible use. Cloncrow Bog (New Forest) 000677 The bog has good hummock/hollow microtopography, pools, quaking areas, a NHA swallow hole, a small flush and forestry on high bog. The cutover supports humid grassland, improved grassland, small areas of Downy Birch (Betula pubescens) 7.79 woodland and scrub, and forestry. The site supports a good diversity of raised bog microhabitats, as well as a number of scarce plant species. Black Castle Bog NHA 000570 The site comprises a raised bog that includes both areas of high bog and cutover bog. Irish Hare, a Red Data Book species, has been recorded at the site. Black 8.43 Castle Bog NHA is a site of considerable conservation significance, comprising as it does, a raised bog, a rare habitat in the E.U.

Offaly Distance from Designated Site Site Code Reason for designation site (km) Lough Ennell SAC & pNHA 000685 Lough Ennell supports a diverse aquatic flora; seven Stonewort species have been identified including two Red Data Book species, Chara denudata and C. tomentosa. Scharff's Char (Salvelinus scharffi), a distinct race of char which was once found only in Lough Owel and Lough Ennell, is now thought to be extinct. Notable aquatic invertebrates recorded from the lake include Tinodes maculicornis, Metalype fragilis, Limnephilus nigriceps (Trichoptera); Picromerus bidens, Monarthia humili (Hemiptera) and Donacia obscura (Coleoptera). This site shares 9.56 an internationally important Greenland White-fronted Goose flock with Loughs Iron, Glen and Owel. Nationally important bird populations have been recorded on Lough Ennell. Lough Ennell is of significance as a highly productive lake which supports a rich variety of lower plant and invertebrate species. Its lakeshore habitats, which include alkaline fen, a habitat listed on Annex I of the EU Habitats Directive, support a diverse flora. These habitats also provide important refuges for wildfowl Rahugh Ridge (Kiltober Esker) 000918 It is a particularly fine esker ridge covered for almost its entire length in woodland.
